Platinum meets its match in quantum dots from coal

October 1, 2014 | by Mike Williams, Rice Univ. | Comments

Graphene quantum dots created at Rice Univ. grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions within fuel cells.

Rating the planet’s oceans

October 2, 2014 8:30 am | Comments

The most comprehensive assessment conducted by the Ocean Health Index rates the Earth’s oceans at 67 out of 100 in overall health. In addition, for the first time, the report assessed the Antarctic and the 15 ocean regions beyond national jurisdiction (high-seas areas). Together with the 220 exclusive economic zones (EEZs) measured in 2012 and 2013, the index now measures all of the oceans on planet Earth.

NIH awards UC Berkeley $7.2 million to advance brain initiative

October 2, 2014 8:28 am | by Robert Sanders, UC Berkeley | Comments

The National Institutes of Health this week announced its first research grants through President Barack Obama’s BRAIN Initiative, including three awards to the Univ. of California, Berkeley, totaling nearly $7.2 million over three years. The projects are among 58 funded in this initial wave of NIH grants, involving 100 researchers and a total of $46 million in fiscal year 2014 dollars alone.

Research confirms controversial Darwin theory of “jump dispersal”

October 2, 2014 8:22 am | Comments

More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage of birds. Though many were skeptical of Darwin's "jump dispersal" idea and instead supported the idea of the use of land bridges, a new computational method now suggests that Darwin might have been correct.

Stressed out: Research sheds new light on why rechargeable batteries fail

October 2, 2014 8:18 am | by Marcia Goodrich, Michigan Technological Univ. | Comments

Drawn relentlessly by their electrical charges, lithium ions in a battery surge from anode to cathode and back again. Yet, no one really understands what goes on at the atomic scale as lithium ion batteries are used and recharged. Using transmission electron microscopy, researchers are now glimpsing what can happen to anodes as lithium ions work their way into them. The “atomic shuffling” these ions perform leads to rapid anode failure.

Agilent to collaborate with Univ. of Toronto on metabolomics solutions

October 2, 2014 7:57 am | Comments

A collaboration has been announced between Agilent Technologies and the Univ. of Toronto’s Donnelly Centre for Cellular and Biomolecular Research to produce a comprehensive metabolomics multiple-reaction monitoring library and methodology, using Agilent’s Infinity 1290 UHPLC, 6460 triple quadrupole mass spectrometry system, and MassHunter Software. The goal is to accelerate quantification of hundreds of metabolically important compounds.

New method helps portable detection of potent “bath salts” drugs

October 1, 2014 11:25 am | Comments

Despite being outlawed in 2012 in the U.S., the synthetic drugs known as "bath salts" are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing low-cost, disposable, mercury-free electrodes that could be the basis for the first portable, on-site testing device for identifying the drugs.

World's first bullet train, made in Japan, turns 50

October 1, 2014 10:23 am | by Emily Wang and Ken Moritsugu, Associated Press | Comments

It was, retired Japanese railway engineer Fumihiro Araki recalls, "like flying in the sky." Zipping cross-country in a super-high-speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday.

All directions are not created equal for nanoscale heat sources

October 1, 2014 10:11 am | Comments

Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A study by researchers from the Univ. of Illinois at Urbana-Champaign has shown that standard thermal models will lead to the wrong answer in a 3-D heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.

“Smart” bandage emits phosphorescent glow for healing below

October 1, 2014 9:37 am | Comments

Inspired by a desire to help wounded soldiers, an international team has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Because oxygen plays a critical role in healing, mapping these levels in severe wounds and burns can help to greatly improve the success of surgeries to restore limbs and physical functions.

Ultrafast remote switching of light emission

October 1, 2014 9:15 am | Comments

Researchers in the Netherlands can now, for the first time, remotely control a miniature light source at timescales of 200 trillionths of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.

Virtual breast could improve cancer detection

October 1, 2014 9:10 am | by Marcia Goodrich, Michigan Technological Univ. | Comments

Only a minority of suspicious mammograms actually leads to a cancer diagnosis, which results in lots of needless worry and spent time for women and their families. Ultrasound elastography could be an excellent screening tool but it requires a lot of skill and interpretation. In an effort to improve results, researchers in Michigan have developed a virtual “breast”, allowing medical professionals to practice in the laboratory.

Gene mutation may lead to development of new cancer drugs

October 1, 2014 8:52 am | by Laura Bailey, Univ. of Michigan | Comments

The discovery of a gene mutation that causes a rare premature aging disease could lead to the development of drugs that block the rapid, unstoppable cell division that makes cancer so deadly. Scientists at the Univ. of Michigan recently discovered a protein mutation that causes the devastating disease dyskeratosis congenita, in which precious hematopoietic stem cells can't regenerate and make new blood.

Government confirms first case of Ebola in U.S.

September 30, 2014 7:38 pm | by David Warren - Associated Press - Associated Press | Comments

Federal health officials on Tuesday confirmed the first case of Ebola diagnosed in the U.S., a patient who recently traveled from Liberia to Dallas and a sign of the far-reaching impact of the out-of-control epidemic in West Africa. The unidentified patient was critically ill and has been in isolation at Texas Health Presbyterian Hospital since Sunday, officials said.
